UMBRA Technologies (US) Inc., UMBRA Technologies Ltd., and UMBRA Technologies Limited (CN) have filed a District of Delaware complaint against Juniper Networks (1:24-cv-01288). The coplaintiffs target the provision of network virtualization products and services with three patents, one familiar to this campaign and two making their litigation debut. The familiar patent has survived reexamination, with the patentability of all claims confirmed, and has (thus far) survived inter partes review (IPR), the Patent Trial and Appeal Board (PTAB) having declined to institute trial in response to a prior defendant’s petition.
